It's relevant because you said you didn't know. The review provides information that helps you to know.

> These activists appear to have followed the federal law enforcement.

Nothing illegal about that at all.

> That highly suggests they knew exactly who they were. ... No reasonable court is likely to determine that they were unaware who they were dealing with.

That's not relevant.

What's your point? No reasonable court would find that the activists did anything wrong, while they certainly would find two federal employees ("officers") are culpable in the murder of one of those activists.

> The officers didn't show up unannounced to the front door of someone who happened to be an activist.

So?
